Hello and welcome to Petco Pet Education Center, formerly Petcoach, Sometimes when animals vomit the pressure on the vagal nerve causes a fainting episode. Animals should recovery completely and quickly from this. Since Sqwrt is so young, and hasn't fully recovered, I recommend you have him seen by a vet. They will check him for an upset stomach, might suggest x-rays or bloodwork, and might give him some medications. Best of luck with Sqwrt, I hope he feels better soon!
